Considering the increasingly complex and interconnected subway tunnels linking cities, this
review argues that the overall reliability of tunnel engineering is crucial for protection when …

The paper presents a systematic review of the research advancements on the resilience of
urban metro systems from the perspective of earthquake engineering. The review covers the …

A 1 g shaking table test is conducted to investigate seismic responses of a segmental tunnel
in sand under near-fault motions. The tunnel model is assembled with segments, bolts and …

Seismic risk is one of the biggest challenges for tunnel safety, and several mitigation
techniques have been proposed to enhance the seismic performance of existing tunnels …

A deep learning method consisting of the gated recurrent (GRU) neural network is proposed
to predict the seismic responses of underground structures in single-layered soil and multi …

The segment joints of a shield tunnel are susceptible to deformation and leakage during
seismic events. In liquefiable strata, opened joints can form seepage channels, which …

The structures on the coral islands are at risk of earthquakes. To study the particular seismic
response of coral sand, the numerical model of the coral sand-pile-superstructure system …

Buoyancy is one of the most serious manifestations of underground structure's instability
during strong ground motions. Soil liquefaction along with significant reduction of its shear …

Utility tunnels in urban areas are generally constructed using the cut-and-cover method, with
shallow depths and large dimensions. Given their high seismic vulnerability, especially in …

The contact interface of the tunnel with composite lining will affect the seismic response of
the tunnel. It is necessary to study the effect of interface properties on the seismic response …
